Hyatt's career began with the
Earle Grey Players, precursor of the
Ontario Stratford Festival, for their Summer Shakespeare Festivals in Toronto and Fall Tours. He performed the roles of Sebastian in "
The Tempest," Hortensio in "
The Taming of the Shrew," and Horatio in "
Hamlet". For the 1956-57 season he traveled to England, performing solo shows at the Arts Club Theatre in London and receiving encouragement and advice from Dame
Flora Robson. On his return to Toronto, Hyatt pursued voice studies with Clara Salisbury Baker, and later with Gladys Shibley Mitchell, eventually sitting for the Licentiate exam in Speech Arts and Drama with
Trinity College, London. While working in radio, Hyatt interviewed celebrities such as
Ethel Waters,
Sophie Tucker,
Jeanette MacDonald,
Arthur Rubinstein and
Lauritz Melchior. It was after interviewing Melchior in New York (an interview subsequently aired on CBC Radio) that the heldentenor gave Hyatt the contacts which led to a New York agent for his solo shows. He stayed under New York management for ten years, living part of each year on
Long Island. In 1970, CHCH Television asked for twelve half-hour programs of material from the solo "A Company of One" shows Hyatt was performing in the United States. These were broadcast in 1971. The same year, Hyatt went on his first European tour, performing eleven shows in Switzerland, including Lucerne, Basel, and St. Gall, and five in the Soviet Union, including Moscow (Tchaikovsky Hall), and Leningrad (Philharmonic Hall). Over the next ten years, Hyatt did three more European tours. ==Solo shows==
